The box which is produced'by the improved method comprises a flat head or body 1 and a marginalflange comprising a body portion 2 extendingaround the edge of the head, and a cover orbinder portion 3 connecting the head and body portion. These parts are preferably made of'paper of suitable thickness' as is usual in articles of this kind,"but' if desired other materials may be used for this purpose.

The head is preferably rectangular, haw

ing a front edge 1, a rear edge 5 and two side edges 6. 6. The'flangecomprises a strip having preferably a central'section-Z'two intermediate 'sections8, 8 arranged onopposite sides of its. central section, andtwoen-d sections 9, 9 arranged; at the extremities-of represents the flange partially the flange. On its inner face or side the flange is provided with transverse front scores or grooves 10, 10 between the central section and the intermediate sections, and with transverse rear scores or grooves 11, 11 between the intermediate sections, and the end sections, respectively, and the ends of the flange are preferably scarfed, as shownat 12, 12, the scarf at one end being preferably on the side opposite to that on the end of the other. The head of the box engages with its front edge against the central flange section, its side edges with the intermediate flange sections and its rear edge with the end flange sections, thereby forming the front, side and rear walls of the box. The length of the central, intermediate and combined end sections of the flange are the same as the length of the front, sides and rear edges of the headso that when these parts are assembled the front corners of the head are in line with or adjacent to the front scorings 10, 10 and the rear corners thereof are in line with or adjacent to the rear scorings 11, 11 of the flange and, as will be seen, the corners of the head enter the grooves at the corners of the flanges. The scarfed portions of the end sections of the flange overlap one another and are united by paste, cement, glue or other kind of adhesive which will answer the purpose.

The binder consists of a strip which is applied lengthwise to the outer sides of the body strip and turned at its forward edge inwardly over the forward edge of the body strip and against the inner side of the same, as indicated at 13 while its lower edge 14; is turned inwardly against the outer or underside of the head, the binder being socured in this position to the body strip and head by an adhesive of any suitable kind, such as glue, paste or cement. If desired,

the binder strip may be of the same length as the body strip, but for certain kinds of boxes this is not necessary. in which case the binder strip is of less length than the body strip and terminates short of both ends of the same, so as to leave the scarf joint between the ends of the body strip on the central part of the rear wall, uncovered by the binder, as shown in Figs. 812. In its completed form the scorings or grooves of the body strip are arranged on the inner sides of its corners and the sides of each groove or score are folded toward each other in bending the sections of the body strip to form a corner, thereby causing the outer side of the corner to be sharp and square. In bending the sections of the body to form the corners those portions of the folded upper edge of the binder on the inner side of the body opposite the corners are deflected into the grooves or scores when bending the body and binder around the head, thereby forming square, sharp or finished corners on the inner sides of the box, as shown in Figs. 12 and 14. It will be noted that the binder is smoothly positioned on the inside of the body at the corners, there being little, if any, bunching of the binder at the corners, the grooves at the corners serving to provide space for the reception of the corners of the binder. In this manner neat square corners are formed on the inside and out side of the box, and a more finished appearance is given to the box, as well as greater space for the contents.

The method of making the elements of the box and assembling the elements into com-- plete box form will now be described. The numeral 15 indicates a continuous body web, one of such length that it may be divided into a plurality of blanks or sections transversely, each section being adapted to serve as a box element or a portion thereof as will appear. This web is preferably of paper of such thickness that grooves or recesses may be made in one face by removal of the material of the web. The web 15 is supplied or fed from a suitable roll of material and should be of such width that when divided into sections transversely of its length, each section will be of a transverse dimension corresponding to the extent or peripheral dimension of the corresponding portion of the box element into which it may be sub sequently folded. In the present instance the element to be formed is a rectangular tubular element, and the width of the body web corresponds substantially to the peripheral dimension of such tubular element. The forward or front end of the web 15 is transversely severed as at 16, at a distance from its end corresponding to a dimension of the element to be formed in this instance the depth of the flange or collar, and successive operations or severings will result in dividing the web on lines transverse to its longitudinal extent into similar sections. Subsequently each section is bent or folded in a plane transverse to, and preferably. at

right angles to the longitudinal extent of the responding to the longitudinal lines of the web, and being continuations thereof. and the opposite ends of the sections are preferably connected so as to maintain the folded condition. resulting in a continuous or tnbular box element such as shown in 1'7, in which the axis of the tube is generally normal or perpendicular to the plane of folding, which may be denominated a box flange or a box collar. or a neck, dependent upon the use to which it may be put. In the present embodiment the opposite ends of the sections are scarfed or beveled as at 12, and the scarfed surfaces abutted with the interposition of adhesive, such as glue, etc., al-

though any manner of maintaining the folded condition of the sections may be used. The direction of feed of the body web is in the'general direction of the longitudinal ex tent of the web, and it will be observed that the web isdivided into sections on lines transverse to the direction of feed, and that p responding to lines of the web which extend transversely of the width of the webs.

By proceeding in the manner" described, the

peripheral dimension of the box element to be formed is taken from the width of the web, and as in many boxes the peripheral extent is greater than the dimension at right angles thereto, the method hereindescribed enables a greater number of elements to be obtained from the same length of web, besides avoiding transfer ofthe sections into different planes before subsequent folding, 'which lattertakes time, andrequires'mechanism to accomplishthe transfer, when performing the method by mechanical means.

As previously described, the sections of the body ,web are folded on lines coincident with the. length of the web, which lines are continuations of similarly located lines of the web, and in. making angular or rectangular elements, as in the box before described, the folding lines are spaced from each other in a manner corresponding to the spacing of the corners of the box. The web is provided with continuous longitudinally disposed recesses or grooves 17,17,

18. 18, on lineswhich are to become. the

foldinglines of the'sections, and preferably the grooves are made by removing or abradi'ng the material of the web to a suflicient depth, as the web is fed, and thewalls of each groove are .angularly arranged, being oppositely inclined from the face of the web towards the center of the groove, so that when the sectionsare. foldedat the grooved portions. the walls. of the respective grooves approach each other, and a square corner results on the outside of the folded element. It will be. obvious also that the inclination of the walls of the grooves may be such that when the fold is completed the opposite walls of the grooves may be. in contact with each other, but it is preferred to leave some space therebetweegn for a purpose which will. hereinafter appear.

. The method so far described also lends itself readily to the productionrof boxes or elements thereof composed of a plurality of superposed strips, blanks. or sections of webs. such as a, collar or flange comprising a body strip and a superposed strip, which latter may completely or only partially cover the body strip,-a-nd may also be utilized to bind or secure the flange to the boX head. In the present embodiment one of the opposed strips is employed not only to cover the other strip, but to bind or secure the flange and head of the box together. i

The numeral 19 indicates a continuous web of flexible paper, preferably glazed on one side,or face, and adapted to serve as the cover or'loinder, above referred to. This cover web is of such length that it may be divided into a plurality of sections transversely, each section being adapted to be connected to a section of the body web.

The width of the cover web 19, approximates,

that of the body web, as shown, su'fiicient uncovered space on the body web being left, in the present instance, to permit the beveled ends of the body sections to be joined. The cover web is supplied from a suitable roll and is fed and guided so that its freeor forward end is positioned relatively to the forward endof the body web so that the ends of the webs may be attached, preferably by foldin the forward end of. the cover web overt at of the bodyweb. To this end, the cover web is coated on one side with glue or other adhesive and engaged near its. front, end with the front part of the under or unscored side of the body web and in a position parallel therewith and with the. front end 20 of the cover web projecting forwardly beyond, thus overlapping the front end of the body web, as shown in Fig.- 2, with the glued side of the cover web. facing the body web, the front ends of the webs being thus superposed and in parallel relation.

After the cover web. has been thus assembled with and pasted to the outer. or under sideof the. body web, the projecting front end of the cover web is folded or turned upwardly, backwardly and downwardly over, or around the adjacent end of the body web, with its glue coated surface againstthc inner side of the body web, whereby the interfolded parts are adhesively secured together in this condition of the cover web, as shown in Fig. 3. V

' After abody section hasbeen cut, as at 21, transversely fromthe front end of the cover web as before described, the same is advanced together with the cover webattachedthereto so as to form an intervening spaceor gap 22 betweenthe rear edge of the severed body section and the front edge of the body web, which space or gap is bridged by that part of the hinder, or cover web trailingbehind the advancing body section aslshown in Fig. 4;. In the case of a plurality' ofwebs the cut 21 is made in the body web at a point ,without those portions of the webs which a e adhesively attached. the

binder web bending away from the body web so as not to be cut by the body cutter. During this forward movement of the body section and the cover web the body web is also moved, or fed, forwardly but less than the body section and cover web, so that the cover web remains with its glued surface in contact with the under or outer side of the front edge portion of the body web, whereby the cover web is dragged with its glue coated surface past this portion of the body web and this glue coated surface, which is on the upper or inner side of the cover web, is eX- posed between the severed body section and the front end of thb body web. After the body section and the body web have been thus separated, that part of the cover web which bridges the space or gap between the body section and body web is severed transversely at a desired point dependent upon the character of the box element to be formed. If a box having a head is to be made, the cover web is severed about midway between the body section and the body web as shown at 21 in Fig. 4, and a strip shaped binder is completed which projects with its rear edge beyond the rear edge of its companion body section, or strip, overlapping the rear edge of the body section. The portion of the cover web in rear of the severing line projects forwardly beyond the front end or edge of the body web, leaving these parts associated in a position'corresponding to that indicated in Fig. 2, ready for turning the front end of the cover web over the front edge of the body web, preparatory to severing the next following sec tions from the respective webs.

In case it should not be desired to utilize an extension of the cover as a means to secure the head to the flange, the cover web may be severed on a line flush with the rear edge of the body section as shown in Fig. 13, and when this collar is folded and its opposite ends connected, as previously de scribed, it may serve as a flange for a box, being connected to the head in any other efficient manner, or it may be assembled with a previously made box and serve as a collar therefor, as shown in Fig. 16.

After the flanges, or covered sections, have been severed from the webs, they are to be assembled with heads to complete the boxes. The heads 1 are preferably rectz-mgular in shape, and are supplied from a suitable source such as a magazine. The heads are delivered successively from the magazine and, while in a vertical position, each is placed with its front or lower edge against the inner side of the central section of the flange adjacent to its lower edge, as shown in Fig. 6. Then the intermediate sections of the superposed strips are simultaneously folded inwardly on the scored lines against the opposite side edges of the head. as shown in Fig. 7. Next the end sections ofv said strips are folded inwardly against the rear edge of the head and at the same time the scarfed parts of the body strip which have been previously coated with glue are lapped one over the other, so as to unite these end sections, as shown in Fig. 8. The rear end portions 23 of the glue coated lower edge of the binder strip are now folded inwardly and pasted against the under or outer side of the head, as shown in Fig. 9, then the side portions 24, 24 of this edge of the binder strip are in like manner turned inwardly and pasted against the under or outer side of the head, as shown in Fig. 10, and finally the front part 25 of this edge of the binder strip is also turned inwardly and pasted. against the under side of the head, as shown in Fig. 11, thereby completing the box.

In thus folding the flange around the edges of the head. the opposite sides, or walls, of each of the scorings are brought towards each other and those portions of the inwardly turned upper edge portions of the cover or hinder opposite the scorings are folded into the latter, as shown in Fig. 14, thereby forming sharp or square corners on the box, both on the outer and inner sides of the same, instead of round corners, as might be the case if these inner scorings were omitted.

In bending or folding the section, or composite strip,-or blank, composed of a pair of web sections, atthe scored lines, a sharp angle results on the outer or convex portion of the folded element, and the cover material on the inside of the strip facing the scores spans the scores at the folded portions. In the embodiment illustrated suflicient space is left between the walls of each score at the corner to receive a portion of the cover material, and the corners of the head. As will hereinafter appear, the folding of the sections, or. strips, is simultaneously accomplished around a rectangular mandrel, and the corners of the mandrel assist in the smooth disposition of the folds of the cover, preferably deflecting portions thereof into the scores or grooves. The cover strip being provided with adhesive, as before explained,

the folded portion of the strip will be adhesively secured to the walls of the grooves when seated therein. 7

By the before described operations not only is the assembly of the webs, the scoring of the sections, the folding of the sections and their assembly with heads most efficiently accom lished, but the time of the operations and the disposition of the webs, enables the webs to be more readily prepared for their subsequent severing, folding, etc.

Any efficient mechanism may be employed to automatically carry out the method herein described, but it is preferred-to employ the machine disclosed in applicants prior application filed April 24, 1909, Serial No.

The numeral 111. indicates a gluing or adhesi 'e applying wheel which is adapted'to apply glue from a suitable reservoir to one scarfed lateraledge of the web, as the web is fed past the same. From the gluer 411 the body web passes above a large roller 413,

which is yie'ldingly upheld by weighted 'cords, so as to provide for feed ofthis web from the scoring wheels intermittently, and "s guided'to the horizontal table 222, passing between oscillatorycurved blades'55, which engage the scoresof the web, and a curved guide, or plate 56, a blade being provided for each score. Rollers are disposed one opposite each score to maintain the blades in the scores, the rollers 65 being y-ieldingly pressed against the web. 225 and 226 indicate knurled feed rollers adapted to yieldingly gripthe body web intermediate its edges.

fore more nearly adjacent the flange folding mechanism, providing sufficient moisture for the joint.

Upon being carried forward by the transferring mechanism comprising the jaws 1&6, 1 17, the flange and binder are assembled with a box head which is preferably of rectangular form. These heads are supplied from a stack contained in an upright magazine 193, and a reciprocatory plunger 197 feeds the heads successively from the bottom of the stack. As the box heads are discharged from the stack they are pressed against the end face of a rectangular former or mandrel 217, being preferably pneumatically held in position thereon. A plurality of formers 217 is employed, one being provided at the end of each of four radiating arms 211 of an intermittently rotating hub 210. Each former is provided with a front jaw 242, which at the proper time is oper ated to clamp the central parts of the adhesively attached body section and cover section against the front side of the former, and Ahead having been pneumatically held thereon, the former is advanced one step and is carried to a position in front of the body and cover assembling mechanism, where it remains momentarily at rest; As the former reaches this last-mentioned position, the box head carried thereby is engaged at its lower or front longitudinal edge with the inner side of the central section of the box flange adjacent to its rear or lower edge,'whic-h latter together with its companion binder is at the same time moved forwardly by the transferring grippers in position to be thus engaged by After this engagement the jaw 242 is operated to clamp the central section of the body and cover against the former, and this clamping continues until the folding of the body and cover and assembly with the head is completed, whereupon the jaw 2&2 is moved to release the elements and permit the box to be removed or ejected from the former.

As the former moves from the body and cover assembling position and approaches the lowermost position of the form-carrier, a preliminary folding or bending of opposite ends of the body and cover against opposite ends of the former is effected by a pair of folding horns 253 arranged respectively on opposite sides of the path of the end portions of the body and. cover in ad- Vance of the position where the former comes to rest for completing the folding of the body and cover. After the former comes to rest in its lower horizontal position, the folding of the intermediate sections of the elements against opposite lateral sides of the former and the adjacent edges of the box head is completed so that these portions or sections of the body and cover are parallel and at right angles to the central or front body section and engage on their inner sides adjacent to their inner edges with the re spective lateral edges of the box-head on the former. The mechanism whereby this is accomplished comprises two side pressing or clamping jaws 255 (only one of which is shown) which are laterally movable towards and from opposite sides of the former 217 when the latter is in position between the same. Then the end sections of the body section and the adjacent parts of the cover or binder are turned inwardly or toward each other and against the back of the former and the rear edge of the box head so that, preferably, these rear sections overlap each other with their scarfed portions and are arranged parallel to the front walls of the box. This operation of folding or bending the rear sections of the body and cover is effected by means of two rear folding and pressing jaws 269.

After the scarfed portions of the flange strip have been overlapped and pressed together as aforesaid, the jaws 269 open so as to be in position to perform a similar operation upon a succeeding flange and binder, but it is preferred to preserve a pressure on the joint for a further period or until the glue sets sufficiently. To this end 270 is a rear clamping jaw adapted to move toward and from the rear side of that portion of the former opposite the joint in the flange, and when the jaws 269 have folded the flange, the jaw 270 is moved to press the joint and continues the pressure during subsequent folding operations, the pressure being relieved in time to permit the box to be ejected from the former.

Further descriptions herein of the folding mechanism is unnecessary for the purpose of this disclosure, it being understood that the above description of mechanism for carrying out the method is merely an embodiment in this application of so much of the prior application as may be desirable in order to facilitate the explanation of the method. It will be understood that the elements of the machine are suitably connected for automatic operation, and that the operations hereinbefore referred to will be so timed as to occur in such sequence as required by the method disclosed.

It will be noted that by the method disclosed a body web having a width of the length of the flange desired is provided, and that the binder web also approximates in width that of the body web. The width of the cover web may be greater than that of the body web, should it be desired to cover the scarfed joint, or to abut the ends of the body section and join them by the cover. Viewed in some aspects, the scarfs may be omitted and any suitable joint provided.

llll) parallel to the length of thewebs and to their general direction of feed when the sections are'regarded as parts of the web; the.

folding lines of' the sections being in effect continuations of similar lines of the webs. In this manner practically the entire length of the webs may be utilized, and a greater number of flanges or binders provided from the same length of web. As the length of the flange or the binder or cover is taken up by the width of the webs, the extent of feed of either of the webs need approximate only matic from beginning to end.

the width of the flange as distinguished from its length. It will be observed that the glue is applied to the scarfed edge by the gluer 411 an appreciable time before the joint is formed so that it has time to become tacky or even dry before the formation of the joint. scoring wheels, or emery wheels, are designed to rapidly rotate so as toremove the material of the web, requiring no such pressure as might produce a bead on the web opposite its scored face. Furthermore, it will be noted that all the operations from the feeding of the webs to the completion of the collars or boxes may be practically con tinuously performed, so that once themachine is set in operation the work is autoi By providing a yielding portion of body web between the scoring wheels, which are continuously operated, and the body web cutter, which latter operates intermittently, either of said operations may be performed irrespective of the other, the slower continuous movement of the web past the grinding or scoring wheels beingcompensated by the more rapid rate of feed due to the intermittent feed rollers 225 and 226. 1

\Vhile the method is herein described in connection with a flange and binder for a box, the names of'the box elements have been chosen merely as a convenient means of explanation. It is obvious that the broad method is not changed by severing the binder web flush with the rear edge of the. flange strip, as illustrated in Fig. 13, so that no trailing portion of binder results. The article thus produced would serve as a box flange when properly attached to a box, or might serve as a collar or neck of a box when properly associated therewith, as illustrated in Fig. 16.

Thus by the above description is disclosed a method of efliciently accomplishing, among others, the objects hereinbefore. stated.

As many changes could be made in carrying out the-above method without departing from the scope of the invention, it is intended that allmatter contained in the above It is also to be noted that the.

into assemblypositi'on with the lateral edges description shall beinterpreted as illustrative and not in a limiting. sense.

Itis alsoto be understood that the language used-1n the following claims is in tendedto cover all of the generic a'ndspecific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

Having described my invention, what I claim as new and desire to secure by Let ters Patent is:

1. The method of making box elements which comprises feeding a web, scarfing the edges thereoi on opposite faces, applying an adhesive to the scarfed edges thereof as it is fed, dividing the web into sections, fold ing the sections on lines transverse of the severed edge, and su'perposing the adhesive supplied scarfed edges after the glue on one edge has become tacky.

2. The method of making boxes which comprises feeding a web,abrading the same to providegrooves longitudinally of the web having angularly arranged walls, dividing the web into sections on lines transverse to the longitudinal extent of the grooves, supplying angular heads, folding the sections around the heads causing the walls of the yrespective grooves to approach each other and receive the corners of the heads, and securing the heads to the sections.

3.
